How to Create a WordPress Database from CPanel

What is a Database?


A database is a collection of organized data. That’s it. WordPress stores all its page, post, category and user data in a database.

MySQL is a database management system (DBMS). It is software which allows you to create, update, read and delete data within a database. A single MySQL installation can manage any number of self-contained databases. You could have one for WordPress, another for Magento, and others for Drupal or whatever you need.

There are plenty of alternatives but MySQL became popular for several reasons:

  • it is free, open source software. It is now owned by Oracle but there are open MySQL-compatible options such as MariaDB.
  • it became synonymous with PHP – the web’s most-used language/runtime which powers WordPress. Both PHP and MySQL appeared in the mid-1990s when web development was in its infancy.
  • it adopts Structured Query Language (SQL) – a (fairly) standard language for creating data structures and data.
  • it is fast, simple to install and has many third-party development tools.

How do Applications Access a Database?


Applications such as WordPress access their data via a database connection. In the case of MySQL, WordPress’ PHP code can only establish a connection when it knows:

  • the address where MySQL is installed
  • the name of the database it needs to access
  • a user ID and password required to access that database

A database “user” account must be defined for WordPress use. It can have a very strong password and set appropriate database permissions.

How is Data Stored?


MySQL and other SQL databases store data in relational tables.

For example, you may have a set of article posts. Each post will have unique data, such as the title and body text. It will also have data used in other posts, such as the category and author details. Rather than repeat the same data again and again, we create separate tables:

  • an author table containing an ID, the author’s name and other details
  • a category table containing an ID and the category name
  • a post table containing the article title and body text. It would point to the author and category by referencing the associated ID number.

SQL databases implement safeguards to guarantee data integrity. You should not be able to reference an author ID which does not exist or delete a category used by one or more articles.

These table definitions and rules form a database schema. A set of SQL commands execute during WordPress installation to create this schema. Only then are the tables ready to store data.

How to Create a Database


Web hosts using cPanel provide a web address , and a user ID and password to gain access. Keep these details safe. Do not confuse them with the database or WordPress user credentials!
If you’re looking for a host that supports cPanel, our web host of choice. All plans support cPanel, and they’ve re-skinned the dashboard to organize everything in a more friendly way.

You view may look a little different but locate the DATABASES section or enter “MySQL” in the search box.
Click the MySQL Database Wizard and follow the steps:

Step 1: Choose a Database Name

Your database requires a name:


The name may have a prefix applied, such as mysite_. Enter an appropriate name such as blog or wordpress and hit Next Step.

Step 2: Create a Database User

You must now define the MySQL user account which WordPress uses to access your database:


Note the user name may also have the same prefix applied (mysite_). In this screenshot, our user ID is mysite_blogDBuser.

cPanel will ensure you enter a strong password. The password can be complex; you will use it only once during WordPress installation. I recommend the random Password Generator:


Make sure you copy the user ID and password to a text file or another safe place before hitting Create User.

Step 3: Set the Database User Privileges

The user created above requires full access to the database during WordPress installation. It runs scripts to create tables and populate them with the initial data.
Check ALL PRIVLEGES then hit Next Step:


cPanel will confirm creation of the MySQL database and user.
